Application filed June 9, 1920. Serial No. 387,611.

T 0 all whom it may concern: Be it known that I, FRANK BABEK, a citizenof the United States of America, residing at Fort Worth, in the countyof Tarrant and State of Texas, have invented certain new and usefulImprovements in Derricks, of which the following is a specification.

My invention relates to derricks for oil wells and the like, and moreparticularly to means for coupling the parts together and bracing thesame; and the object is to provide a simple construction for buildlngand .mounting derricks at relatively small ex-v pense and by which theparts are easily and quickly and safely coupled together and to.

tion of the timbers relative to the coupling.

Fig. 3 is an enlarged view, showing parts of the horizontal timbers inhorizontal section and showing the end of one of the uprights. Fig. 4:is a vertical section of one of the couplings and showing the positionof the timbers relative to the coupling. Fig. 5 is a detailed sectionalview, showing the manner of making the shanks of the braces engage thecross bars.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The improved derrick is composed of several series of upright members orthe derrick is built in sections and the sections are coupled together.Members 1 are coupled to members 2 and members 2 are coupled to members3 and members 3 are coupled to members 4. The means for couplingtheupright members together consist of metal couplings 5 which have flanges6 and open- Specification of Letters Patent. Patented NOV. 23, 1920'. I

ings 7 are made through the flanges to re- 1 ceive the bracing rods. Thebracing rods 8 consist of two members achustably connected byturnbuckles 9 and the rods all have bent shanks 10 which are projectedthrough openings of the flanges 6 and engage the crossbars 11, shownparticularly in Fig- 5. The

couplings 5 and the cross-bars l1 are-centrally positioned relative toeach other and the ends of the uprights 1 meet at the vertical centersof the couplings 5. The object is to have one set of cross-braces 11brace the ends of two setsof uprights l. The diagonal braces 8 tightenthe couplings 5 against the ends of the cross-braces 1 1,.and by reasonof the couplings being countersunk on the ends of the uprights 1, thediagonal braces 8 tighten the uprights 1 in the couplings 5 and the endsof the uprights bear against each other. The ends of the shanks 10substantially inclose the ends of the cross-braces 11 against theflanges 6. It will be seen that all the parts cooperate in bracing thederrick when the turnbuckles 9 are tightened on the diagonal braces 8.The.

shanks 10 of the diagonal braces 8 position the ends of the cross-braces11 against the couplings 5. V 'VVhat I claim, is,- A lerrick composed ofsets of couplings vertically disposed and having horizontally projectingflanges, sets of uprights having thelr meetlng ends received in saidcouphngs at, the vertical centers thereof, cross-bars abutting againstsaid couplings and against centrally said flanges, and diagonal bracesbent at their ends and projecting through said flanges and bent aboutsaid cross-bars and binding said cross-bars against said flanges andagainst said couplings and binding the mieting ends of said uprightsagainst each ot er.
